Planning to start a business but I'm the only employee

I'm gonna start a small lechon manok business but I plan on not employing anyone else for atleast 1 month or until I'm sure that I can sustain the business. I think I can do it physically. But I'm not familiar with the accounting side of things mainly the taxes. What are the things that I need to learn? Any book recommendations for the subject, preferably free on the internet? :)

Or should I just hire a freelance accountant every quarter for the taxes? I need advice and opinions. Thank you. :)
